The present invention pertains to a novel planer in which the tool canbe adjusted to any angle corresponding to the surface to be dressed. Theinvention is moreover applicable to other surfacing machines when asmooth out surface is needed.

The principal object of the invention, as indicated, is to provide aplaner having an angularly adjustable tool shaft. Another object is toprovide a simple and practical means for fixing the ends of the arbor.

A further object is to provide a planer having the described propertiesand constructed in a simple and economical manner.

In the accomplishment of these objects, the device includes arectangular table carrying a pair of uprights laid transversely at thecenter and spaced a small distance apart. Each upright has a largesquare opening and a groove or slot in the frame thus formed. Each suchslot extends along one side and the top of the frame, and the opposedslots receive slide screws which are carried by a block or spacer. Thescrews are secured by wing nuts at both ends. The block receives theshaft of a portable driving motor, and the shaft in turn carries theworking tool.

The opposite end of the shaft is mounted in a bearing carried by anangle iron which is secured to one of the uprights by another screwmeans.

The table top has a central transverse removable strip to permit removalof the uprights when desired.

The invention i fully disclosed by way of example in the followingdescription and in the accompanying drawings in which:

Figure 1 is a perspective view of the device;

Figure 2 is a plan view;

Figure 3 is a section on the line 3-3 of Figure 2;

Figure 4 is a section on the line 4-4 of Figure 2; and

Figure 5 is a detail section.

Reference to these views will now be made by use of like characterswhich are employed to designate corresponding parts throughout.

In Figure l is shown a table having a horizontal top I supported on fourcorner legs 2. The lower ends of the legs are joined by stretchers 3which serve to support a pair of uprights 4. The latter extend above thetop l and lie transversely at the center there-of and spaced apart ashort distance. These member are in the form of plates having each alarge square opening 5 above and. receiving the table top. The opening 5leaves a frame, and each frame is formed with a slot 6 along onevertical side and the top there of, with a bend 1 between the side andtop portions.

At the uprights 4 the table top has a separable transverse strip 8. Thestrip is formed w th tenons 9 receivable in grooves I0 formed in theadjacent parts of the table top. The grooves are extended at I l intothe uprights 4.

Between the uprights 4 and at the slots 6 is mounted a block 12 havingscrew studs l3 extending from its sides into the respective slots. Awing or other nut 14 is carried by each screw l3 at the outer surface ofthe adjacent upright for adjustably securing the block between theuprights.

The block I2 is extended at its base by a plate 15 which supports anelectric motor I6 outside the uprights. The block is actually a bearingfor the motor shaft 11 which carries a cylindrical planing tool I 8lying within the openings 5. The free end of the shaft is received in abearing i9 formed in a U-shaped plate 20 lying between the respectivesides of the opposed frames. The sides Zl of the U-member 2!] aresecured against the sides of the frame by the device shown in Figure 3.A screw 22 extends from one of the sides 2! loosely into a tube 23 onthe other side. A lock nut 24 on the threads of the screw bears a ainstthe end of the tube 23 whereby to spread the sides 2| against the sidesof the uprights. For easier manipu ation. the lock nut is formed as ahand wheel as illustrated.

In t e use of the device, if a single plank is to be planed, as shown inFigure 1, the shaft I1 is mounted horizontally. In this position thenuts I l are tightened to secure the bearing block I2. Next, the nut 24is turned to secure the bearing 49 between the frames 4 as described.

For thicker plank or for forming angular surfaces, the hearing I? and I9are individually adjusted to the desired positions and secured thereinas already set forth.

The removable strip 8 permits removal of the frames or adjustment of theshaft I1 to a steep angle, as shown in dotted lines in Figure 4.

Although a specific embodiment of the invention has been illustrated anddescribed, it will be understood that various alterations in the detailsof construction may be made without departing from the scope of theinvention as indicated by the appended claims.

What I claim is:

1.. A planer comprising a table having a top, a pair of hollow framesmounted transversely thereof in spaced parallel relation, a tool shaftlying between said frames, bearings for the ends of said shaft, one ofsaid bearings comprising a U-member having its sides engaging saidframes, screw means for spreading said sides against said frames, meansfor individually adjusting said bearings vertically in said frames, anda motor for driving said shaft.

2. A planer comprising a table having a top, a pair of hollow framesmounted transversely thereof in spaced parallel relation, a 1 091 hflfllying between said frames, bearings for the ends of said shaft, slots inopposed vertical sides of said frames, screw studs extending from one ofsaid bearings through said slots, nuts on said studs,

the other bearing comprising a ,g n emlloer haw ing its sides engagingsaid frames, screw means for spreading said sides against said frames,and a motor for driving said shaft.

3. A planer comprising a table having a top,

a pair 9 'hp'llew frames 1-mt ;,l tra ersely of said shaft, means forindividually adjusting said bearings vertically in said frames, and amotor for driving said shaft, said table top having a separabletransverse strip positioned between said frames, to form an opening inwhich an end of said shaft may be inserted.
